I'm 16 weeks 5 days and have noticed little flutters (kind of feels more like gas to me than flutters but i know its not) and was trying to get the baby to move as before I never really realized that's what it was until after. So I shined a light and was poking my belly a bit and didn't feel anything so I kind of gave up. But I laid out and stretched a bit and put my hand on my belly and within a minute it felt like he was doing little baby somersaults lol

It was the most activity I've felt at all and today is the first day I got to sit and actually know what was happening while it happened!
